The RCM+ Rack Mounted Horizontal Cable Manager with Cover is a double‑sided, plastic finger–style solution designed to provide an organized horizontal pathway for cabling on both sides of a two‑post rack within the same RMU spacing. Constructed from durable 14‑gauge steel with UL 94V‑0 black plastic components, it features plastic cable‑management fingers for proper bend‑radius control and an open‑back design that enables smooth cable transitions from front to back. The low‑profile rear design offers easy access behind patch panels, while snap‑on, removable, hinged aluminum doors open past 180° and stay upright for convenient cable handling. Styled to complement RCM and RCM+ vertical managers, the standard versions integrate seamlessly with RCM vertical cable managers, and the extended DX series fingers deliver 45% more cable capacity for use with RCM+ managers. For added convenience, #12‑24 mounting hardware is included to ensure quick and reliable installation.
